About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SCA
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation with ease. The Ø12 mm bore uses an M5x0.8 air port and an M6x1.0 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments.
The riveted round body incorporates fixed TPU bumper pads to soften stroke-end impacts without adding bulk. Because this SKU includes the -S magnet, it supports CMSG, DMSG and EMSG position switches. Plan for roughly 34 N of actual work at 0.5 MPa, which translates to lifting about 2.9 kg vertically with a 2:1 safety margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SCA Is Used
Small Part Ejection
Uses the 56.5 N push stroke to knock lightweight plastic mouldings off an injection press conveyor without damaging the part surface.
Pivot Actuation
Leverages the CA clevis rear cover to swing a small guide flap on a PCB assembly line, accommodating angular movement during repositioning.
Lab Dispenser Trigger
Taps the 2.9 kg vertical lift capacity to depress a reagent pump plunger in a humid analytical instrument enclosure.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SCA the Right Cylinder?
When sizing this actuator, the smaller Ø10 bore yields 39.3 N of push, while stepping up to the Ø16 bore provides 100.5 N at 0.5 MPa. This model features a CA rear pivot cover, making it ideal for clevis mounting where the rod path requires angular alignment. The integrated -S magnet allows for direct sensor mounting.
Note that a standard double-acting cylinder drifts if air pressure drops or the valve is centred, as the TPU bumpers only decelerate the stroke end and act as neither a lock nor a brake. To suspend a vertical load safely during an air loss event, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SCA FAQ
At 0.5 MPa it pushes with 56.5 N and pulls with 42.4 N. At 0.7 MPa the push is 79.1 N and the pull is 59.4 N. The theoretical maximum force is 11.5 kgf at 1.0 MPa. The air port is M5x0.8.
This model uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion; for variable cushioning consider the MIC variant. Because it has the -S magnet, you can mount CMSG, DMSG or EMSG switches for position detection.
